Does practice make perfect? We’ll find out tonight as New Directions competes in “Sectionals,” the heavily anticipated episode that will serve as our last hit of Glee until—all together now!—April 13. Let’s review the available information about the big show after issuing this SPOILER ALERT:

• In the trailer for “Sectionals” that aired last week, Emma says to Will, “I want to take the kids to Sectionals,” to which he responds, “The wedding’s on Saturday… your wedding.” And Rachel braces for a Quinn beatdown.

• In a clip from “Sectionals” released by Fox (see below), several members of New Directions are nervous that Rachel will discover the truth about Quinn’s baby and blab it right to Finn, who’ll freak out, throwing the club into disarray on the eve of Sectionals.

• A press release from the network also hints that “when Quinn’s secret unravels, the club may not be able to recover in time to compete,” “Sue’s scheming hits an all-time high,” and “with Emma and Ken’s marriage looming, Will makes a decision that could change his life forever.” Songs to be covered include: “And I Am Telling You I’m Not Going” from Dreamgirls, Barbra Streisand’s “Don’t Rain On My Parade,” The Rolling Stones’ “You Can’t Always Get What You Want” and Kelly Clarkson’s “My Life Would Suck Without You.”

Surely you have a theory or three on tonight’s episode. Does McKinley take home the trophy? Will Emma make it to the altar? Does Will forgive Terri? Will Quinn sing another rather inappropriate song to a child? All predictions are welcome. And, of course, feel free to use this space during the episode to discuss and dissect the action as it unfolds.
